class_docstr: Encapsulates all the validation logic required by Opacus.
  Also works as a namespace to hold registered validators and fixers.
docstr: Fix the module and sub_modules first, and then run validation.
  
  Args:
      module: The root module to be fixed and validated
      **kwargs: Arbitrary keyword arguments.
  
  Returns:
      Fixed module.
  
  Raises:
      UnsupportedModuleError in case of validation failures.
